// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configJAEGER_AUTHORIZATION_HEADERAuthorization HTTP header to be added into the requests for querying traces over Jaeger API (for ex. Basic <Basic Auth Header>)
configJAEGER_PORTHTTP or gRPC API port of the Jaeger instance to access. The default value is 16685 for the gRPC API and 16686 for the HTTP API.
configJAEGER_PROTOCOLAPI protocol of the Jaeger instance to access. Valid values are GRPC and HTTP. The default value is GRPC. Valid
configJAEGER_URLHTTP API (HTTP JSON (/api/v3/)) or the gRPC API (gRPC/Protobuf (jaeger.api_v3.QueryService)) URL of the Jaeger instance to access.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
